Duct Fitting Database - ASHRAE ashrae duct fitting database version 60005 free
I understand you’re looking for information regarding the ASHRAE Duct Fitting Database (DFDB) , specifically version 60005, and how to access it for free.
Here is a clear, factual write-up about this topic, including what the database is, the status of version 60005, and the legitimate ways to obtain it at no cost.
Most versions of the ASHRAE DFDB require a license. However, Version 60005 was released during a transitional period in the early 2000s. Unlike later versions that are locked behind paywalls or subscription models, Version 60005 escaped into the wild.
The DFDB is a digital library of pressure loss (loss coefficient) data for hundreds of HVAC duct fittings — elbows, tees, transitions, takeoffs, dampers, and more. It is based on ASHRAE Fundamentals Handbook, Chapter 34 (Duct Design) and ASHRAE Research Project RP-1493.
Introduction to the ASHRAE Duct Fitting Database The ASHRAE Duct Fitting Database (DFDB) is the industry-standard reference for loss coefficients for HVAC duct fittings. It is the digital embodiment of the data found in the ASHRAE Handbook of Fundamentals and ASHRAE Research Project 1053-RP. Engineers and HVAC designers use it to calculate pressure losses in duct systems accurately, enabling energy-efficient building design.
What is Version 60005? Version 60005 refers to a specific build or release of the ASHRAE DFDB software. Over time, ASHRAE has released several versions (e.g., 5.00.00, 6.00.00, 6.00.05). Version 60005 is an older, legacy version of this tool. It is no longer the current release (newer versions include updated fittings, improved interfaces, and bug fixes). However, it remains functional and useful for basic duct design and educational purposes. ASHRAE Duct Fitting Database (DFDB) version 6
Can You Get Version 60005 for Free? Yes and no – depending on the source and intended use:
Legacy Freeware Status (Historically Accurate):
ASHRAE previously offered older versions of the Duct Fitting Database (including versions 3.x, 4.x, and some 5.x builds) as free downloads on their website, often bundled with the ASHRAE Fundamentals Handbook CD-ROM or as a standalone tool for members and educators. Version 60005 was never officially marketed as a “free, standalone public download” in the way open-source software is, but it was distributed at no cost to ASHRAE members and through some academic channels.
Current Official ASHRAE Policy:
The latest versions of the DFDB (version 7.x and above) are commercial products, sold through the ASHRAE Bookstore. However, ASHRAE still provides older versions for free to support legacy projects and low-budget users. As of the last known distribution, version 6.00.05 was made available for free download from the official ASHRAE website under “Archived Software.”

Be cautious of third-party websites claiming to offer “ASHRAE Duct Fitting Database 60005 free download.” Many such sites bundle malware, adware, or outdated, corrupted files. Always download directly from ASHRAE.org or a trusted academic/hvac engineering repository. ASHRAE permits free use of legacy versions for non-commercial, educational, and internal professional use, but redistribution of the installer is generally not allowed.
Conclusion
Version 60005 of the ASHRAE Duct Fitting Database is a legacy tool that can be obtained legally for free directly from ASHRAE’s website. It remains valuable for basic HVAC pressure loss calculations, especially for students, small firms, or engineers maintaining older systems. For new projects requiring the latest fittings and modern OS support, consider purchasing the current version – but for a zero-cost, reliable solution, version 60005 is an excellent resource.
Recommendation: If you are unable to locate version 60005 on ASHRAE’s current site, contact ASHRAE Customer Service directly. They can often provide direct links to legacy software upon request.
